A core raider mage in our guild is getting pretty frustrated with his level of DPS in the raids, he is doing okay but with the legendary cloak/ reasonable gear feels he should be doing a lot more. He has attempted to highlight the areas he needs to improve on but I feel we could use some outside help and expertise. Any feedback/ criticism is welcome, thanks!
His damage is a bit low. But everything seems pretty close to okay IMO. His bomb uptime is the only issue. Sub 80% on a lot of fights. No excuse to have it below 95%. Invokers is around 90% on a lot too. That should be above 95%. His crit isn't super amazing, but its good. Fire is RNG and I've had nights were RNG was not on my side and I have have plenty more crit than he does. A little tweaking of his buff/bomb uptime and his dps should improve.
He's 0.52% over the hit cap, which is just rating thrown away. Sub 80% bomb uptime hurts, a lot, you're missing both Bomb damage and Pyromaniac uptime, that hurts a lot. For somebody who has 4 piece T15 and that many pyro crits his combustion average is low, but I guess Combustion is just a wet noodle anyway nowadays, and his 2500 mastery rating doesn't help.
I'd try to up Invoker's Energy a bit, but like the previous poster said, get that Bomb uptime up to 95%.
